How to Make or Create a Radio Friendly Mix/Master -Broadcast Ready

This a complete tutorial on how to make your mix or music ready for radio broadcasting or any types of broadcasting such as in television, etc.

The fact that broadcasting follows an entirely different audio specification than the usual CD audio master you bought in stores or the MP3 masters you downloaded from iTunes, etc. If you submit music which is not radio or broadcast ready; it is either denied for broadcasting simply because it is not following specifications or it sounds very awful on air. Why? It is because broadcasting systems have their own compressors and limiters

One truth that you should know is that radio and television systems already include their own compressors and limiters. This equipment’s are designed to make their broadcast output as loud as possible while controlling the accidental spike on loudness that goes out on air.

However very loud type of music which has a very small dynamic range can sound awful in radio because broadcasting compressors/limiters further compressed or limit them! This results to pumping, squashed and distorted music on air.

The Solution: Allow more “Dynamic Range” on your Music

The straightforward solution would be submitting music that has a very wide or big dynamic range. The question is how much and how to measure dynamic range?

Using a standard radio broadcasting compressor (Orban Optimod Broadcast Processor) that music needs to have dynamic range of around 8dB to maintain the desired punch and clarity on air. Smaller than that (< 8dB or less), the music would now start to sound squashed and bad (distorted also).

So how would you measure the dynamic range of current masters that you are planning to submit to the radio or any broadcasting medium? Follow the steps below:

Step2.) Fully install foobar2000 audio player in your computer. After installation, try playing at least one song to make sure it works. If you are using an external audio interface/ASIO instead of a normal PCI soundcard, you can configure it as follows (by going to Library – Configure). Then under “Playback” click “Output”.

Output configuration

In the above screenshot, foobar2000 is configured to work with Saffire Audio and set to output 24-bit audio.

Step3.) Once it’s working; you can install the dynamic range component. You need to download it here.

Step4.) Extract the DLL content to your desktop.Step5.) Go to your computer program files directory. This is usually found in:C://Program Files

In one of the folders, click foobar2000; then click “components” folder. You need to copy the DLL file: foo_dynamic_range.dll to this folder. This is how it looks like after copying:

Step6.) Restart foobar2000 by closing and starting it again. Open your highest resolution master (e.g. 24-bit/44.1KHz). Or if you don’t have one, you can play your mp3 or CD audio masters. Once it’s loaded in the foobar2000 playlist and playing, right click on the track title and you should see the “Dynamic range meter” option.

Step7.) To measure the dynamic range of the audio being played, simply click “Dynamic range meter” and it directly gives you the result:
